“…Due to several conditions such as fire and skeletonization, there are difficulties in identification using biometrics. As, teeth have distinctive characteristics and high resistance it plays an excellent source of DNA especially when there is a failure in the conventional method [10,12].…”

Forensic Odontology is a branch of forensic science involves in human identification through dental tissues or more specifically teeth when there is the destruction of body tissues in criminal mass disasters. The importance of Forensic Dentistry in recent days lies mainly when there is little remaining material to perform such identification has led dentists working with forensic investigators to become more aware with the new molecular biology technologies. In the last few years, DNA analysis methods are more commonly applied in the forensic cases due to its uniqueness in identification of human remains even in the deceased state. DNA is a genetic material which is unique to each individual. In oral cavity and mainly in tooth structure DNA is found to be in abundant and hence it can be an excellent source of genomic DNA. Recently, DNA profiling has high reliability and is accepted as legal proofs in courts. This article mainly focuses on an overview of DNA and their applications in the last few years, highlighting its importance in forensic investigation.

“…1 As the dental tissues are resistant to environmental assaults such as incineration, immersion, trauma, mutilation and decomposition they are therefore invaluable for identification on fragmentary adult skeleton. 2,3 Teeth are readily accessible for examination and since no two teeth have similar morphology, they form an excellent forensic tool for sex determination. 3 Various features of the teeth, such as morphology, crown size, and root lengths, are characteristic for male and female sexes.…”

Introduction: Sex determination plays an important role in forensics. On average, males possess larger tooth crowns than females in contemporary human populations, although the degree of dimorphism varies within different populations. Ground sectioning of teeth can provide an accurate measurement of enamel and dentinal thickness and can be used for gender determination in forensic analysis. Aim: The main aim of this study is to evaluate sexual dimorphism in human premolars using longitudinal ground sections. Materials & Method: In this study extracted premolar teeth of males and females were taken. Longitudinal ground sectioning of these teeth was made and later examined under light microscope under customized grids. Results: Data was statistically analyzed and results were tabulated. It was found that enamel area and average enamel thickness was higher in females than males and coronal dentinal areas were more in males. Conclusion: Results of this study suggest that the differences in crown morphology among males and females can be used as a potential tool in forensic analysis.

DNA has been the hereditary material of almost all organisms, including humans. In recent years, DNA fingerprinting technique has been the most renowned method used in forensics for human identification. Extracting DNA from routinely used samples becomes very challenging in degraded and fragmented human remains, i.e., in cases of incineration, mutilation, and fire. Due to the unique placement of teeth in the jaw and their composition, DNA material present gets additional protection compared to bones or other sources of DNA. Hence, it frequently becomes the only source of DNA that would be available in such situations for identification. DNA fingerprinting helps unravel the mysteries within the mouth, including the manifestations of diseases in the oral cavity. There have been highly improved methods described for analyzing various forensic scenarios and DNA extractions. Identifying the deceased victims, the missing person, the masked culprits involved in crime, the paternity issues, interpretation of genetic diseases, and determining the ancestry account for some uses of DNA fingerprinting. This review briefly summarizes recent literature and current knowledge of forensic odontology, DNA content, and distribution in teeth and its preservation. This also intends to emphasize the role of the tooth being a valuable source of DNA and thereby discusses some of the methods of recovery of DNA from teeth, ways of DNA analysis, and highlights the benefits and challenges regarding the DNA extraction protocol in the field of forensic odontology.
